My dissertation’s focus is on turbulence statistics, second and fourth-order correlations, con- vective velocities, acoustic Mach numbers and flow physics relevant to the efficiency of noise emission in supersonic hot jets. My research included the experimental investigation of cold and hot, supersonic jets via advanced laser diagnostics and time-resolved shadowgraphy.Part of my dissertation work was in the development of time-resolved Doppler Global Ve- locimetry (TR-DGV) instrumentation for high speed flows and included the development of a 64-channel multi-PMT-camera unit with FPGA back-end for the planar operated TR-DGV in- strument. Additionally I worked on the implementation of multi-point TR-DGV in the large- scale NATR facility at NASA Glenn Research Center, Aero-Acoustic Propulsion Laboratory (AAPL) which I visited for 4 weeks in the Fall of 2014.

Biotransport and Optics Lab | AEThER LabMy main work was in injection experiments for brain cancer therapy using light guiding fiber optical needles. I developed experimental protocols and data processing software for carrying out dye injection experiments in agarose models. Further I assisted in invitro with dog brain injection experiments under MRI supervision.

Turbulence Research Group - Dr. Roger L. SimpsonMy Masters research was in the experimental and numerical (1-D models, CFD) investigation of particle acceleration in supersonic flows/particle shock-wave interaction. A main compo- nent was the development and application of one-component Laser Doppler (LDV/LDA) Instrument with an elongated measurement volume for acceleration measurements. Addi- tionally I have gained experience on simplified modeling of magnetic particle targeting in rheological flows, combining several models to predict magnetic targeting for small blood vessels.

University Of Applied Sciences Trier

During my time in Trier I worked on computational fluid dynamics (CFD) of rotational flows (turbo machinery application) and subsonic coaxial multiphase jets for industrial mixing applications using ANSYS Fluent.
